Cleaning Procedures

1 1 standard precautions
1.1 Standard Precautions

Standard precautions are applied as a first-line approach to infection control. These form the basis for your decision-making and practice. Standard precautions are a set of guidelines based on the assumption that all blood and body fluids are potentially infectious.

1 1 standard precautions11
1.1 Standard Precautions

In the context of sterilising practice and ALL the Standard Operating Procedures, standard precautions include:

  • Hand Hygiene
  • Hand cream – approved by infection control – not in packing area
  • Personal Protective Equipment
      • Gloves
      • Face shields, hair protection, safety glasses and masks
      • Fluid resistant gowns/aprons
  • OHS Requirements
1 2 soiled pickup collection
1.2 Soiled Pickup Collection
  • Standard Precautions - PPE
  • Contaminated items - dedicated collection trolley/cart
  • Keep instrument sets together
  • Follow the designated route with trolley (OHS)

Collection containers are:

  • puncture-resistant
  • leak-proof and made of either plastic or metal
  • with a lid or liner that can be closed
1 2 soiled pickup collection13
1.2 Soiled Pickup Collection

Cleaned items must be dried prior to transport

Reusable instruments cassettes and single items placed into designated transport containers

Secure single loose items

Don’ts

Place heavy instruments on light instruments

Lift above shoulder height

Containers should not exceed 10 kgs

containers for transport from surgery
Containers for Transport from Surgery
  • with a lid
  • easily cleaned
  • puncture and leak proof
  • kept in a clean, dry condition
  • not overloaded
  • carefully packed
    • sharps recognised
    • facing same direction
1 3 sorting prior to cleaning
1.3 Sorting Prior To Cleaning

Instruments and items sorted by;

  • Type
  • Method of cleaning e.g. Manual , ultrasonic,

Instruments and items are checked for;

  • Completeness
  • Defects
  • Sharps or blades that have not been removed
  • Heavily soiled items
  • Single use only items are not to be returned for reprocessing

Report concerns to supervisor

cleaning
Cleaning
  • Cleaning removes organic and inorganic soil, blood, fats etc which contain pathogenic micro-organisms
  • Cleaning minimises contamination levels of bioburden (number of micro-organisms) prior to sterilisation
  • For sterilisation to occur the aim is to have a low number of micro-organisms present on instruments
cleaning17
Cleaning

Steam will not penetrate contamination left on instruments

If the item is not clean it won’t be sterilised

1 4 chemical detergent mixtures
1.4 Chemical & Detergent Mixtures
  • Breaking down and removal of
    • Blood, proteins and debris (organic soils)
    • Medicaments and chemicals (inorganic soils)
    • Breaks water tension – surfactant
    • Keeps the soils suspended in the water
  • Must be an “instrument” detergent. DO NOT use household type
  • Compatible with instruments and equipment
  • Material Safety Data Sheets (MSDS) – ChemAlert
  • Appropriate storage requirements
1 4 chemical detergent mixtures19
1.4 Chemical & Detergent Mixtures

Manual cleaning agents

  • Mild alkaline instrument detergent - optimal pH: 8.0 -10.8
  • Low foaming properties
  • Non-corrosive
  • Non-toxic
  • Non-abrasive
  • Free rinsing
  • Bio-degradable
  • Preferably liquid
  • Use and rate of concentration: as per manufactures instructions
1 4 chemical detergent mixtures20
1.4 Chemical & Detergent Mixtures

Mechanical cleaning agents

  • Mechanical washer manufacturer’s requirements

e.g ultrasonic or washer/disinfector

  • May be stronger alkaline pH range: 8.0-11.5
  • Biodegradable
  • Nonabrasive
  • Low foaming
  • Free rinsing
  • Preferably liquid
  • Use and rate of concentration: as per manufactures instructions
1 4 chemical detergent mixtures21
1.4 Chemical & Detergent Mixtures
  • Enzymatic Cleaners
  • Includes enzyme pre cleaners and enzymatic detergents
1 4 chemical detergent mixtures22
1.4 Chemical & Detergent Mixtures

Drying Agents/Rinse Aids – Washer disinfectors

  • Surfactants that “wet” the final rinse water
  • Automatically dosed into the final rinse water
  • Spreads evenly over a surface instead of beading
  • Beaded water leaves mineral salts
  • Not as effective on plastics
  • Load instruments and metals on the top racks with plastics on the bottom
  • Plastics on edge to allow drainage
1 4 chemical detergent mixtures23
1.4 Chemical & Detergent Mixtures

Acid Base Agents

  • Only on stainless steel surfaces
  • Only intermittently descaling or destaining
  • Dissimilar instruments should not processed at the same time
  • Mix the agent as per manufacturers instructions
  • Only mix when required and discard at end of the day
  • OHS -Chemical manufactures instructions , including safety precautions, dilution and instrument compatibility
  • OHS - Rubber or nitrile gloves
1 4 chemical detergent mixtures24
1.4 Chemical & Detergent Mixtures

Lubricants

  • Water miscible – able to mix with water
  • Compatible with the sterilizing agent
  • As per manufacturers instructions
  • Instrument stiffness needs to be investigated
  • Lubrication used intermittently
  • Routine use = heavy contamination
1 5 pre cleaning
1.5 Pre Cleaning
  • Pre cleaning (initial cleaning) allows for the removal of visible blood, body fluids and debris from items prior to cleaning (definitive cleaning). Pre cleaning shall be undertaken as soon as possible (e.g. during and post procedure chairside).
  • If blood, proteins and other debris are allowed to dry or remain in crevices and joints, the instruments become very difficult to clean and are prone to stiffness and accelerated corrosion.
1 5 pre cleaning26
1.5 Pre Cleaning
  • Pre cleaning can be performed by methods such as dry wiping, damp wiping or use of a commercially available single use only instrument sponge
  • Place the dry wipe, damp wipe or sponge on the bracket table and carefully wipe the instrument across the material
1 5 pre cleaning27
1.5 Pre Cleaning

Rinsing removes excess blood and debris

  • Prevents blood and debris drying on items
  • As soon as possible - post procedure
  • Reduces bioburden - micro-organisms will multiply rapidly
  • Use warm water
    • hot water coagulates protein
    • cold water - congeals fats
1 6 hand cleaning for immersible items
1.6 Hand Cleaning For Immersible Items
  • Automated cleaning of instruments is the preferred practice, but not always feasible
  • Identify instruments that cannot be immersed under water for manual cleaning
  • Two dedicated sinks large, deep enough for practical use
  • Separate hand washing facility
1 6 hand cleaning for immersible items29
1.6 Hand Cleaning For Immersible Items
  • Warm water – potable (drinkable)
  • Instrument brushes various sizes
  • Disposable low - lint cloth
  • Suitable instrument detergent Ph: 8
  • Pressure equipment
    • High pressure water
    • Air pressure
    • Disposable Syringe
  • Non abrasive pad
double sink operation
DoubleSink Operation
  • The first sink is to be always used for the initial rinse of instruments only and does not need to be cleaned between use.
  • The second sink is to be used for the cleaning and the final rinse of instruments and only needs to be cleaned between these two activities if the instrument cleaning water is discoloured or cloudy.
  • NB all sinks must be cleaned at the end of the day
single sink operation
Single Sink Operation
  • The sink is to be cleaned with a detergent impregnated wipe between the first rinse of the instruments and the filling of the sink for cleaning the instruments.
  • Following cleaning of the instruments and before the final rinse the sink only needs to be cleaned with a detergent impregnated wipe if the cleaning water is discoloured or cloudy.
  • NB all sinks must be cleaned at the end of the day,
1 6 hand cleaning for immersible items32

1 6 hand cleaning for immersible items39
1.6 Hand Cleaning For Immersible Items

Problems associated with incorrect drying

  • Items should NOT be air dried/ dripped dry

Good conditions micro-organisms multiply in 20-30 minutes

  • Wet packaging result in unsterile item
  • Can cause rusting, corrosion, pitting to the item
1 7 hand cleaning for non immersible items
1.7 Hand Cleaning For Non-immersible Items

For those items that are unable to be submerged under water

  • Some items e.g surgical handpieces and attachments, may need hoses or caps attached to prevent water entering delicate parts
1 7 hand cleaning for non immersible items41
1.7 Hand Cleaning For Non-immersible Items
  • Initial rinse - Some items may be gently rinsed with warm water to remove gross soil as per manufacturer’s instructions.
  • Initial rinse - Some items may be rinsed using a low lint cloth immersed in water if the item cannot be placed under gently running water
  • Fill sink correct ratio of warm water and suitable detergent
  • Items are wiped using a clean cloth immersed in the clean, warm water with detergent added
  • The cloth is squeezed (wrung out) to prevent water entering the instrument, it is damp only, and not dripping wet
1 7 hand cleaning for non immersible items42
1.7 Hand Cleaning For Non-immersible Items

The impregnated damp cloth is rubbed over the item

May need to be repeated depending extent of soiling

Handpieces that cannot be immersed in water follow the manufacturer’s instructions

Non-immersible cannulated items - the manufacturer’s instructions must be adhered to in relation to flushing and brushing

1 7 hand cleaning for non immersible items43
1.7 Hand Cleaning For Non-immersible Items

Following washing the detergent must be removed

FINAL RINSE - Using a damp clean low lint cloth (that has not been in contact with detergent), wipe over the item to remove the detergent. Note if a demineralised/reverse osmosis water system is installed, rinse with demineralised/ reverse osmosis filtered water

These steps may need to be repeated to remove all traces of detergent (Dry as per instructions in SOP 1.6 immersible item)

Purpose

Ultrasonic cleaning is a form of mechanical cleaning that uses high frequency ultrasonic waves (cavitation) that dislodges fine particles from the surfaces of instruments.

slide49

Ultrasonic cleaning is an effective cleaning method for instruments prior to the reprocessing

1 8 ultrasonic cleaner50
1.8 Ultrasonic Cleaner
  • Minimises manual cleaning
  • Does not disinfect instruments
  • Remove debris using cavitation (sound waves)
  • Detergent as per manufacturer’s instructions
  • Requires degassing before use
  • Rinsing after use (if no further washer/disinfector processing)
  • OHS – do not immerse hands when operating
  • OHS – aerosols – use lid when operating
  • OHS – noise – use lid & hearing protection
  • OHS – dry hands – when handling electrical leads and turning on or off at power point.
